![]() There is some prototype code in the sandbox, but nothing is ready yet. That’s roughly where we are so far - of course, some things will be adapted and changed on the way. The system defines methods to look them up: foreach ($entity->getPropertyDefinitions() as $name => $definition) " to access the node author’s user name could work like that: echo $node->user->entity->name->value įor that, all to work the system maintains so-called “property definitions", which are a bit similar to $field and $instance for fields but are there for all properties. Next, dealing with entity references should become easier as well, such that the system cares about loading referenced entities for you. That makes it easier to deal with single-valued properties, while it makes sure the code does not break if a single-valued field gets changed to be multi-valued later on (or vice versa). If the array access is omitted, it will just default to the first property item. However, we actually know there can be only one title yes? So you can also do: echo $node->title->value the node’s image alt text could be accessed like that: echo $node->field_image->alt Īs all entity properties have to follow the structure, it works the same way for others like the node title: echo $node->title->value In order to ease access to the properties (in default language) we plan to implement magic getters, so that e.g. You may notice that no language is in there - the idea is that this all just works with a reasonable language default, while it’s possible to get properties in a certain language by specifying an optional language parameter in the property getter. Thus, an entity consists of multiple entity properties, which consist of one or more property items (just as field API $items), which each have one or more values (just as field API’s columns). So let me shortly explain the overall architecture of what we currently have or plan for: The idea is that *every* entity has to follow the following data model: Once this works out, the plan is to convert the first entity type and post a patch for further review to the core queue ( here). Work on that is currently done in a sandbox, where we’ll flush out the API with a test entity type. See the Entity Property API meta issue for a more complete list of planned features. So there will be no need for entity wrappers - all the easy API and information will be directly available in $entity. If you know the Entity property information system of the Drupal 7 Entity module, it’s a bit similar to that, but instead of adding an extra layer above the existing entities, it’s about supporting it natively. The API should allow for introspection, so that it’s possible to look up the defined properties of an entity type in advance. What?Īs we’ve outlined in the WSCCI Web Services Format Sprint report we want to have a modern OOP, interface based API for properties. But furthermore, with classed entity objects as the basis we can improve the developer facing API and make it easier to access property and field values (I’m looking at you, $entity->field_body). So fields will be entity properties working with the same API as well! Then, it’s about being able to introspect what’s going to be in an entity - regardless of whether it has been added by a module or by the user via field UI. That is what the new Entity Property API is supposed to change: It’s about providing a unified interface to entity properties *and* fields, avoiding the split between fields and non-field properties. For those points, we need to know what’s in an entity! Yes, we can look up the fields, but there are also base entity properties and further stuff modules put on entities, which both are no fields so we do not know anything about them. * field_ui_base_route = "entity.qwiz_type.While the conversion to full CRUD for entities and classed objects for Drupal 8 made good progress, we’ve not yet reached the goals of fully translatable entities and having a default entity serialization for import/export, content staging and web services. * "collection" = "/admin/structure/qwizard/qwiz", * "canonical" = "/admin/structure/qwizard/qwiz//delete", ![]() * admin_permission = "administer quiz entities", * revision_data_table = "qwiz_field_revision", ![]() * "html" = "Drupal\qwizard\QwizHtmlRouteProvider", * "access" = "Drupal\qwizard\QwizAccessControlHandler", * "delete" = "Drupal\qwizard\Form\QwizDeleteForm", ![]() * "edit" = "Drupal\qwizard\Form\QwizForm", * "add" = "Drupal\qwizard\Form\QwizForm", * "default" = "Drupal\qwizard\Form\QwizForm", * "views_data" = "Drupal\qwizard\Entity\QwizViewsData", * "list_builder" = "Drupal\qwizard\QwizListBuilder", * "view_builder" = "Drupal\Core\Entity\EntityViewBuilder", * "storage" = "Drupal\qwizard\QwizStorage", The entity was created in a custom module, which I can modify. I need to add a field to it, and I want to do it through the UI. ![]()
